Since the mid-1990s, violent crime rates fell among young juveniles (under age 15) and older adults (over age 24), but the scale of these changes was overwhelmed by the size of the violent crime drop among older juveniles (ages 15-17) and young adults (ages 18-24). The declines in the rate of murder arrests involving juveniles and young adults completely reversed the increases seen prior to 1994, bringing murder arrest rates down to levels below those of 1980. In general, the changing arrest rates for older juveniles mirrored those of young adults during the 1990s and early 2000s. Robbery was the exception. The changes in robbery arrest rates of older juveniles were far more dramatic than those seen among young adults.
